Mass-radius diagrams showing planets with radius of R<4 R_⊕, and age in the range 200–400 Myr (black symbols), to which TOI-2076 belongs. Black dots indicate planets with a measured mass, while black triangles represent planets for which only a mass upper limit is available. Grey dots represent a sample of older planets with masses and radii known at least at 30 and 10%, respectively. To produce this plot, we considered the known planets collected by the Exo-MerCat tool⁷(Alei et al. 2020, Alei et al. in prep.) by merging the information from the main exoplanets online catalogs (e.g. NASA Exoplanets Archive and Exoplanets Encyclopaedia). The locations of the three planets of the TOI-2076 system are indicated with orange triangles within the appropriate age bin by considering the mass upper limit in Table 3, while the orange star symbols represent the positions of TOI-2076 b, c, and d if we consider the mass obtained with the modelling of the SERVAL RVs (wavelength range no. 3) with a multi-dimensional GP using the BIS. Diagonal dashed lines indicate the location of planets with an equal density.
